Is this necessary? I don't see where it's used in this patch.

If this method is ever called simultaneously on different threads (i.e., web thread vs. main thread), there's a possibility of a race condition. Perhaps dispatch_once() here instead?

Ditto.

It is necessary to look like an AVPlayerLayer, it is accessed by AVPlayerLayerView in AVKit.

WebVideoFullscreenInterfaceAVKit is only ever accessed from the main thread. All the jumping between threads happens in WebVideoFullscreenControllerAVKit.

Yes, dispatch_once is the right way to initialize these. I'll change that.

Ditto.

Why the .get(), since setLayerHostView takes a RetainPtr<WebLayerHostView>&&?

I'll remove this.
